Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix RL1G confirms the tape and reel shipping format containing 2000 units per reel. Confirm the component meets Pb-Free requirements as indicated by the G suffix. Ensure the TO-92 package style matches the required pinout configuration for the target circuit design.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with a -30 V collector-emitter rating and -100 mA continuous current capacity is required. The B series gain band provides moderate amplification suitable for general-purpose tasks. Consider thermal derating factors if operating above 25°C ambient conditions.

Single Bipolar Transistors Part Context

This part belongs to the BC556/BC557/BC558 family of PNP silicon amplifier transistors produced by onsemi. The BC558 variant specifically provides a -30 V breakdown voltage, distinguishing it from the higher voltage BC556 (-65 V) and intermediate BC557 (-45 V) models within the same product line.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include other manufacturers' BC558B variants in TO-92 packages. Verify that replacement parts match the -30 V collector-emitter voltage and -100 mA current ratings to ensure functional equivalence.
